Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention, for example, in a one-box type or cab-over type vehicle, introduces traveling wind from the opening of the front bumper,
The present invention relates to a traveling wind introduction structure that blows air to an air conditioner, an engine mur, and the like, and particularly to a structure that can improve ventilation efficiency without increasing the number of parts.

[0002]

2. Description of the Related Art For example, in a one-box type automobile, an engine is mounted near a lower portion of a driver's seat and an intake device for introducing outside air into the engine is arranged. As shown in FIGS. 5 and 6, this intake device generally has an air intake chamber 21 disposed between a front cross member 26 and a front bumper 22 and a duct inlet 21a thereof.
Is located near the rear of the front grille 23 above the front bumper 22 to prevent rainwater from entering and
The extension end of the duct outlet 21b of the chamber 21 is connected to an air cleaner 24 arranged near the engine 25. Further, in the above-mentioned automobile, in order to blow traveling air to the radiator 27, the engine room, the air conditioner, etc., an opening 22a is conventionally formed in the widthwise central portion of the front bumper 22, and the opening 22a is formed through the opening 22a. I am trying to introduce a driving wind.

[0003]

However, in the above-mentioned conventional traveling wind introducing structure, since the intake chamber 21 is disposed at a position that traverses the opening 22a of the front bumper 22, the intake chamber 21 travels. This hinders the introduction of wind (→ mark in FIG. 6) to the radiator 27 and the like, and moreover, it is easy to be caught in the lower portion of the cross member 26 from the opening 22a. Therefore, there is a problem that ventilation efficiency is poor. Here, for example, Japanese Utility Model Application Laid-Open No. 55-25503 proposes a structure in which a wind guide plate is attached to the lower edge of the radiator and the traveling wind is introduced by the wind guide plate. However, in this case, there is a problem in that the cost increases as much as the mounting of another component.

The present invention has been made in view of the above conventional circumstances, and an object of the present invention is to provide a traveling wind introduction structure for an automobile capable of improving ventilation efficiency without increasing cost.

[0005]

SUMMARY OF THE INVENTION In view of the above, the present invention provides a vehicle traveling method in which an intake chamber is provided between a front bumper and a front cross member, and an opening for introducing traveling air is formed in the front bumper. In the wind introduction structure, the intake chamber is arranged in a space between a portion below the opening of the front bumper and the front cross member, and the upper surface of the intake chamber is substantially continuous with the lower edge of the opening. It is characterized in that it is formed so as to form a surface.

[0006]

According to the traveling wind introduction structure for a vehicle according to the present invention, the intake chamber is arranged in the space below the opening of the front bumper and the front cross member. It will be hidden in and will not hinder the introduction of running wind. Further, since the upper surface of the intake chamber is formed so as to be substantially continuous with the opening, the upper surface of the intake chamber functions as a baffle plate, so that the introduced running wind is circulated below the cross member. Can be supplied to a radiator or the like without needing to improve the ventilation efficiency. Furthermore, in the present invention, since the structure is such that only the arrangement position and shape of the intake chamber are changed, there is no need for a separate part as in the above publication, and there is almost no increase in cost.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 are views for explaining a traveling wind introduction structure of an automobile according to an embodiment of the present invention. In the figure, reference numeral 1 denotes a one-box type vehicle to which the structure of this embodiment is applied, an engine 2 is mounted near a lower portion of a driver's seat 1a of the vehicle 1, and a radiator 3 is provided in front of the engine 2. It is arranged. Further, a front cross member 4 having a generally U-shaped cross section is provided below the front end of the automobile 1, and both ends of the cross member 4 are provided on left and right sides of a vehicle body (not shown). It is joined to the front end of the side member.

A resin-made front bumper 6 extending in the vehicle width direction is provided under the front panel 5 of the automobile 1, and the front bumper 6 is supported by the cross member 4. Openings 6a are formed in a grid pattern at the center of the front bumper 6, and the radiator 3 is located behind the openings 6a. A license plate 7 is attached to the lower center of the opening 6a.

An air intake chamber 8 of an intake device for supplying air to the engine 2 is arranged in a space A formed between the cross member 4 and a portion 6b of the front bumper 6 below the opening 6a. The chamber 8 is supported by the cross member 4 via a bracket (not shown). The intake chamber 8 is formed in a size and shape that substantially fills the space A, and its dimension in the vehicle width direction is set to be substantially the same as the width dimension of the radiator 3. The chamber 8 has a capacity of about 3 liters, for example. An outside air introducing duct 9a is connected to the intake chamber 8, and the duct 9a is located behind the license plate 7 and extends upward. Further, one end of a connecting duct 9b is connected to the left end portion of the intake chamber 8, and an extended end of the duct 9b is connected to an air cleaner of the intake device.

The upper surface 8a of the intake chamber 8 is formed in an inclined shape so as to be located on a line connecting the lower edge of the opening 6a at the lowermost end of the front bumper 6 and the upper edge 4a of the cross member 4. ing. As a result, a substantially continuous surface is formed from the lower edge of the opening 6a to the upper edge 4a of the cross member 4.

Next, the function and effect of this embodiment will be described. According to the traveling wind introduction structure of the present embodiment, the intake chamber 8 is arranged in the space A between the lower portion 6b of the front bumper 6 and the front cross member 4, so that the intake chamber 8 is the same as the front bumper 6 described above. Since it is hidden, it does not hinder the ventilation when introducing traveling wind. Further, since the intake chamber 8 cannot be seen from the outside, it is possible to avoid deterioration of appearance.

Further, in this embodiment, the upper surface 8a of the intake chamber 8 is formed in a slanted shape so as to form a substantially continuous surface from the lower edge of the opening 6a to the upper edge 4a of the cross member 4. Therefore, the upper surface 8a of the intake chamber 8 serves as a baffle plate, and the traveling wind can be efficiently blown to the radiator 3, the air conditioner and the like. In addition, this improvement in efficiency is achieved by the intake chamber 8 described above.
Since it is realized only by changing the arrangement position and shape of the, it is possible to suppress the cost increase without the need for separate parts.

Furthermore, in this embodiment, since the intake chamber 8 is formed to have a size that fills the space A to the maximum extent, the capacity of the intake chamber 8 can be increased, and the intake noise to the air cleaner can be reduced accordingly.

In the above embodiment, the case where the upper surface 8a of the intake chamber 8 is formed in an inclined shape so as to form a continuous surface from the opening 6a to the upper edge 4a of the cross member 4 will be described as an example. However, the present invention is not limited to this. For example, as shown in FIG. 4, the upper surface 8a of the intake chamber 8 may be formed to be substantially horizontal and may be substantially flush with the opening 6a. Also in this case, the upper surface 8a of the intake chamber 8 functions as a baffle plate, and the effect of improving ventilation is obtained.

Although the one-box type automobile is shown in the above embodiment, the present invention is of course applicable to other types of automobiles.
